Featured Reviews

Vagner Martins - PeerSpot reviewer
Enhanced data security with seamless integration and static website capabilities
S3 is a great service offering numerous possibilities. It allows for storing objects and files of various types. I appreciate its capability to create static websites and integrate with services like CloudFront, EC2, and DynamoDB. Despite being focused on security, I leverage features such as cryptography and integration with CloudTrail.
PriyankShrivastava - PeerSpot reviewer
A workhorse that enables high availability but support has room for improvement
There is always room for improvement. When a product is marketed, many claims are made, but in reality, it does not always perform as expected. The usability and real-time capabilities could be enhanced. The product can be difficult to use compared to how it is marketed. Technical support also lacks a timely response.
